Electric vehicles gain more importance due to environment protection policies as well as the technology of electric motors and batteries are in constant improvement. Some countries and companies are developing electric water crafts where usages could be military, transportation as well as private high speed and high efficiency vehicles. Progressive adoption of the water jet pump is achieved as cheaper materials are available on the market and the technology makes more affordable to implement these high speed propellers for water crafts. Materials must be taken into account in order to prevent corrosion, as well as the water jet pump must be designed according to a high efficiency electric motor as to minimize problems such as cavitation for maximum durability of the pump.In this thesis, designing a water jet pump for watercraft powered by an electric motor configure making a step forward on high quality electric vehicles design.

Machine shape optimization using the CFD analysis is currently a widely used tool for improving the parameters of the machines. The subject of this work is the investigation of the influence of shape change on the boat engine parameters (flow, thrust, efficiency). The scaled model of the boat engine will be investigated. The main tool for the investigation will be the CFD computations. Validation of the CFD results should be done by the comparison with experimental data.
The thesis contains:
Description of the boat engine including the main parameters.
Review of the CFD and experimental methods.
Description of the physical and material models used for CFD simulations.
CFD simulation of the flow inside the boat engine.
Comparison of the experimental and CFD results.
Evaluation and discussion of results.
